IVMS101 (the InterVASP Messaging Standard) is the global data-interoperability standard for Travel Rule messaging between VASPs - developed by the Joint Working Group on InterVASP Messaging Standards (JWG) which includes representatives from FATF + the major Travel Rule solution providers + industry bodies. IVMS101 standardises the data fields for originator + beneficiary + VASP identification + transfer metadata for interoperable VASP-to-VASP messaging. Competing implementation networks include: TRP (Travel Rule Protocol); TRUST (Travel Rule Universal Solution Technology, established by Coinbase + Anchorage + Robinhood + others); Sygna Bridge; OpenVASP; Notabene; Sumsub Travel Rule; Veriscope; Synchrology; Shyft; 21 Analytics. Network interoperability remains imperfect - many VASPs operate multiple Travel Rule networks to communicate with counterparties on different networks. The 2024 Targeted Update encouraged industry to converge on a small number of interoperable networks + adopt IVMS101 as the lingua franca.
